More than 50,000 of people marched in Moscow Sunday to honor slain opposition politician and Kremlin critic Boris Nemtsov, NBC News reported. Nemtsov, a frequent critic of Russian President Vladimir Putin, was supposed to appear at a Sunday rally protesting Russia's role in the fighting in Ukraine. The rally was converted into a memorial march after the 55-year-old was gunned down late Friday on a street near the Kremlin. Many marchers carried signs with a single word: "Fight" and clutching images of Nemtsov.
